500 for positioning, the rubber pads mounted at the bottom of the fault 456 are made of nitrile rubber, the container can be prevented from being damaged when the fault of the aligning plate 454 is inserted into the top of the container (after the container 500 is fixed, the servo motor II 452 should be started again to drive the gear IV 453 in the opposite direction, the gear IV 453 drives the rack II 455 meshed with the gear IV, the rack II 455 drives the aligning plate 454 to move upwards, and the aligning plate 454 is packed up), when the driver finishes fixing the container 500 by the hanging beam 300, the driver operates the crane to slowly lift the hanger body 100, at this time, because the distribution positions of the goods in the container 500 are different, the weights of the left end and the right end are different, the container 500 and the hanging beam 300 fixed at the top are inclined, at this time, when the horizontal monitor 313 senses that the hanging beam 300 is inclined leftwards, the two groups of speed reducing motor 204 are started to drive the gear I205 to rotate anticlockwise at this time, the rack I302 meshed with the two groups of speed reducing motor are driven to move leftwards, the rack I302 drives the hanging beam 300 in the hanging frame 200 to move leftwards, the gravity centers of the hanger 200 and the hanging beam 300 are shifted leftwards to offset the weight excess at the left end of the container 500 and slowly shift to the gravity center of the container 500, at the moment, the container 500 and the hanging beam 300 are gradually balanced, then the two groups of speed reducing motors 204 are closed, when the horizontal monitor 313 senses that the hanging beam 300 inclines rightwards, the two groups of speed reducing motors 204 are started to drive the first gear wheels 205 to rotate clockwise, so that the gravity centers of the hanger 200 and the hanging beam 300 are shifted rightwards to finish the balance work, the stability during transportation is improved, the side clamp can be better leveled and fixed when being placed on a transport vehicle (when the side clamp 350 contracts and extends out, the fixed seat 305 at one end of the side clamp 350 drives the fixed beam 306 and the sliding seat 307 to slide on the inner wall of the sliding track 308 to play a limiting role and make the side clamp 350 more stable when expanding and contracting), after the container 500 and the balanced container are fixed, at this time, the first servo motor 402 is started to drive the second gear 403 to drive the third gear 404 meshed with the second gear to rotate in the direction opposite to the first direction, the third gear 404 drives the rotating shaft 405 to rotate inside the limiting plate 406, the rotating shaft 405 drives the arc-shaped plate 407 to turn downwards, so that the metal block 410 inside the arc-shaped plate 407 is just attached to the electromagnet 312 on the side surface of the hanging beam 300, the electromagnet 312 is powered on at this time, (the electromagnet 312 is powered off when the arc-shaped plate 407 turns upwards), the metal block 410 attracts the electromagnet 312 to complete the fixing of the arc-shaped plate 407, at this time, the hook 409 at the end part of the arc-shaped plate 407 is just hooked at the bottom of the front end edge and the rear end edge of the container 500 (as shown in fig. 8), the container 500 is tightly hooked, the anti-falling protection of the container 500 is completed, the rubber layer 408 is made of polypropylene rubber and is used for protecting the arc-shaped plate 407 from being eroded by rainwater or wind, the service life of the arc-shaped plate 407, the rubber pad 311 is made of nitrile rubber, the nitrile rubber has the advantages of wear resistance and softness, and the contact surface of the right-angle hook 351 and the container 500 is protected from being damaged.
The above is only a preferred embodiment of the present invention, and any person skilled in the art may modify the present invention or modify it into an equivalent technical solution by using the technical solution described above. Therefore, any simple modifications or equivalent replacements made according to the technical solution of the present invention belong to the protection scope of the present invention.
